Built to battle skyscraper fires, this jet-propelled water cannon is
the new pride and joy of China’s Luoyang City fire department. It is
made from a jet-fighter engine and is capable of spraying 4 tons of
water per minute.

The price tag of $456,000 seems to be worth it, as the water is said
to blast fast enough to separate fires from their oxygen supply. It has
a range of almost 400 feet and can rotate a near-full 360 degrees. And
if the firefighting business slows down, China can always deploy the
cannon to clean the sure-to-be-megadirty streets of its future megacity.
